Part of the Advances in Experimental Medicine and Biology book series (AEMB, volume 255)


The existence of a plasmalemmal ATP-dependent Ca2+-pump that extrudes Ca2+ out of the smooth muscle cells against its electrochemical gradient is well established and has been studied by measuring the ATP-dependent accumulation of Ca by microsomal fractions of smooth muscles.
